About This Camera
Camera Location & Hazard Overview
The A20 Sidcup Bypass near County Gate runs between Sutcliffe Park and Frognal Corner as a fast dual carriageway with no at-grade junctions once past New Eltham — meaning once traffic gets moving here it tends to stay moving, but any blockage has nowhere to escape to. County Gate itself refers to the gap in the central reservation near the playing field, a detail that trips up drivers trying to interpret older sat-nav instructions.
Traffic Pattern & Congestion Trends
Morning peak 07:15–09:00 carries commuters from Sidcup, Chislehurst and further into Kent toward Lewisham and the A2/A20 split at New Cross. With no traffic lights on this stretch, congestion typically starts at either end and backs up along the whole bypass rather than building gradually. Evening traffic 16:30–18:00 mirrors this in reverse.
Traffic Fines & Camera Enforcement
This section carries a 50mph limit through parts of the bypass with fixed-point camera enforcement, and the central reservation gap at County Gate is restricted to authorised access only — right turns across it from Sidcup Road are banned. ULEZ applies across Bexley 24/7 — check tfl.gov.uk/ulez if unsure about compliance.
Road Closures & Alternative Routes
If the bypass is solid here, the only realistic local alternative is dropping onto Sidcup High Street or the older A222 route through Foots Cray, both adding considerable time but keeping you moving rather than static with no exit. For M25-bound through-traffic, it's often faster to sit tight than attempt a diversion with no clear rejoin point. A breakdown on this stretch with no hard shoulder is a genuine emergency rather than an inconvenience, so having emergency car breakdown cover that guarantees a fast response matters more here than on almost any other road covered on this site.
Driver Safety & Local Tips
Because this stretch has no junctions to bail out at, check the camera before committing — a live accident here is often quicker to wait out than to route around, given how few exits exist along the whole bypass.
ULEZ & Emissions
The London Borough of Bexley operates entirely within the Ultra Low Emission Zone (ULEZ), which is active 24/7, every day of the year. Non-compliant vehicles (pre-Euro 6 diesel / pre-Euro 4 petrol) face a £12.50 daily charge. No Congestion Charge applies in this borough. Check your vehicle compliance at tfl.gov.uk/ulez.
Parking near A20 Sidcup Rd/County Gate, South London
The Sidcup Bypass has no roadside stopping anywhere along this stretch — it's a fast dual carriageway with no verge parking and enforcement of the 50mph roadworks zones taken seriously. For genuine parking, Sidcup town centre a short distance away has Bexley Council car parks and CPZ-controlled streets requiring a permit during the day. Locals treat this bypass purely as a through-route and would never consider stopping here even briefly; if you need to pull over, wait until you reach Sidcup or New Eltham where there's proper off-street provision.
